The film centers on Megan Harris (Grimes), who can’t stop dreaming about a night that never happened. It involves a rowdy party, her sorority sisters and a hazing ritual that ended in the death of an innocent girl. She awakens from the nightmare every morning to find she’s sustained a traumatic injury and her brain can no longer retain the day’s memories once she has fallen asleep. Her quest to find the truth before she sleeps sends her on a downward spiral that has her wondering whether she can even trust herself.

Keegan will play Dr. Trent Rothman, Megan’s friend from college and now her doctor, who is trying to help get her short-term memory back.
